    Interpretation: Findings from above Table

    • Inflation Rate: Continuously Declining
    • Cost of Inputs: Declining
    • Labour Productivity: First Increasing and then Declining
    • Inflation Expectations: Declining
    The aggregate supply curve shifts to the right as productivity increases or the price of barrels of oil falls, making a combination of lower inflation, higher output, and lower unemployment possible.

    A fall in oil prices (and a fall in firms costs) will shift the short-run aggregate supply (SRAS) to the right, causing lower inflation and higher real GDP.

    The declining inflation expectations meet the declining inflation rate due to a rightward shift in aggregate supply.

    If we expect prices to decline in future, the demand for wages declines and so firms reduce their prices. Thus the short term supply [SRAS] would increase.

    Economics Concept Introduction

    Introduction:

    Aggregate or Total Supply, otherwise called as total yield, is the aggregate supply of products and services delivered inside an economy at a given general price level in a given period. It is depicted by the total supply curve, which indicates the connection between price levels and the amount of yield that organizations will provide. Normally, there is a positive connection between total supply and the price level.

    A shift in total supply can be ascribed to various factors. These incorporate changes in the size and nature of work, mechanical developments, technological advancements, an expansion in compensation, an expansion underway costs, changes in producer taxes, subsidies and changes in inflation. A portion of these elements prompts positive changes in total supply while others make total supply decrease.
